Which statement is true?

A) In the short run and the long run the perfect competitor will break-even.
B) In the short run and the long run the perfect competitor will make a profit.
C) In the short run the perfect competitor may make a profit or take a loss.

In the short run, a perfect competitor may make a profit or take a loss depending on market conditions and the ability to cover variable costs. However, in the long run, perfect competition implies that no firm can make an economic profit as new firms will enter the market and drive down prices until firms earn only normal profits or break-even. Therefore, statement A, B, and D are false.
